specific Embodiment approach 1

[0029] Specific implementation mode one: combine Figure 1 to Figure 3 The present embodiment is described in detail. The telescopic wind turbine impeller described in this embodiment includes a main shaft 1, n sets of impeller frames 2, n sets of blades 3 and bearing housings 4, wherein n is not less than 1 Positive integer; each group of impeller frames 2 includes a first impeller frame 21 and a second impeller frame 22; the first impeller frame 21 and the second impeller frame 22 take the main shaft 1 as the axis of symmetry, and are fixedly mounted on the main shaft in mirror image symmetry 1; the blade 3 includes a first blade 31 and a second blade 32; the first blade 31 is movably mounted on the first impeller frame 21, and the second blade 32 is movably mounted on the second impeller frame 22.

specific Embodiment approach 2

[0030] Embodiment 2: The difference between this embodiment and Embodiment 1 is that the first blade 31 and the second blade 32 are connected as a whole through a connecting member 35 and move synchronously. Other compositions and connection methods are the same as those in Embodiment 1.

specific Embodiment approach 3

[0031] Embodiment 3: The difference between this embodiment and Embodiment 2 is that the connecting member 35 is a steel wire rope, a chain or a plate material, all of which are detachably connected to the first blade 31 and the second blade 32 . Other compositions and connection methods are the same as those in the second embodiment.

Abstract

The invention provides a wind turbine impeller used for solving the problems that an existing wind turbine impeller is low in wind sweeping capacity, not enough in power and the like. The impeller comprises a spindle, n sets of impeller frames, n sets of blades and a bearing pedestal, wherein n is a positive integer which is not smaller than 1; each set of impeller frames comprises a first impeller frame and a second impeller frame; the spindle 1 serves as the symmetry axis of each first impeller frame and the corresponding second impeller frame, and each first impeller frame and the corresponding second impeller frame are fixedly mounted on the spindle in a mirror symmetry mode; each set of blades comprises a first blade and a second blade; each first blade is movably mounted on the corresponding first impeller frame, and each second blade is movably mounted on the corresponding second impeller frame; each first blade and the corresponding second blade are connected into a whole through connecting components and move synchronously; the spindle 1 is perpendicularly mounted on the bearing pedestal. The wind turbine impeller has the characteristics that the wind sweeping capacity is enhanced, the structure is simple, the electricity generation power range is wide, the application range is wide, and the like.

Description

technical field [0001] The invention relates to a wind turbine impeller and belongs to the technical field of wind power generation. Background technique [0002] In recent years, with the continuous improvement of people's living standards, the consumption of energy has also increased, and the problem of energy shortage has gradually attracted people's attention.
